CLUTCH.

Application filed April 10, 1924.

This invention relates to'clutches and more particularly tocluteli-setting devices which may be used for various purposes, but isespecially adapted for use in hoisting or 5 hauling engines forcontrolling a clutch to couple or disengage selectively the drum thereofwith or from a power driven shaft.

The objectof the invention is to provide an eiiieient clutclrsettingmechanism of the l above character which will be compact and easilyoperated, and obviate the use of thrust pins or thrust sleeves hithertoemployed in clutch setting operations.

Vith these ends in view the invention consists in the novelconstruction, adaptation, and combination of parts hereinafter describedand claimed.

In the accompanying drawings,-

Figure 1 is a transverse vertical section, talen substantially on brokenline 1 1 of Fig. 2, of a portion of a log-hauling engine With apparatusembodying the present invention applied thereto. Fig. 2 is a sectionalview on broken line 2 2 of Fig. 1, and with the web of the driven Wheelpartly broken away to disclose the lever assembly em` ployed in theoperation of the clutch. 3 is a side elevation of Fig. 1 and a manuallyactuated means for controlling` the clutch.

In said drawings, the reference numeral 5 represents a shaft,hereinafter designated as the drum shaft, which is journaled in abearing 6 of a standard 7 which constitutes a part of the frame of theengine or machine. Carried upon said shaft for yindependent rotarymotion is a cable Winding drum 8 having at one of its ends a peripheralflange 9. Keyed or otherwise rigidly secured tothe drum shaft 5 is aWheel 10 provided With spur teeth 11 in mesh with the teeth of a spurpinion 12 (Fig. 2) upon a power driven shaft 13 whereby the ivheel 10and the drum shaft are rotated.

Preferably the drum clutch is applied tothe outer cireuniferentialsurface of the drum flange 9 and, as illustrated, consists of twocomplementary clutch bands 14 connected from one end of each to studs 15which are secured to the wheel at diametrically opposite sides of thedrum shaft. rlhe other ends of the respective bands are connected to pinelements 16 of arms 17 Which are carried by shafts 18 which arejournaled in bearings provided in the Wheel 10 and located in proximityof the af0resaid studs. As shown in Fig. l, the shafts Fig Serial No.705,433.

opposite sides of a hub 24 Which is looselyV mounted upon the drum shaftand 'between the wheel l() and the shaft bearing 6. Said hub is providedwith peripheral teeth 25 and constitutes a gear which is driven byengaging a'gear 26 upon one end of a shaft 27 which entends through abearing 23 of the standard 7 to receive a gear 29 at its other end.

'p Both of these gears 26 and 29 are keyed or otherwise rigidly securedto the shaft 27.

The gear 29 meshes with a gear 30 Which isA rotatable loosely upon thedrum shaft 5 or, as shown in Fig. 1, upon a bushing 31 pro vided by anextension or hub of a gear 32 which is rigidly secured as by means of akey tothe drum shaft.

Meshing with the gears and 32 respectively are gears 33 and 34 which aresecured as by means of a key to a shaft 35 Which is journaled in a frame36 arranged to be swung about the axis of the drum shaft.

The proportional sizes of the gears from 25-26, 29-33 and 34-32 are suchthat their relative speed ratios Will be such that when actuated by thedrum shaft the gear 25 will rotate at the same speed and eoincidentlywith the drum shaft.

As shown, the frame 36 is formed of two parts 37 and 38 which aresecured together as by means of bolts 39, the frame part 37 being`iournaled on the drum shaft and the other part 38 being journaled on aboss of the standard 7.

An extension 40 of the frame 36 may be employed as a handle forregulating the position of the frame to control the clutch mechanism aswill presently be explained.

In Fig. 3, l illustrate the frame 36 connected by a reach rod 41 with anoperating lever 42 ful-crumed at 43.

The operation of the invention is) as follows: Assuming the drum shaft 5is driven in either rotary direction, the Wheel 10 and the gear 32 whichare keyed to the drum shaft will rotate therewith.
